Here, we have assigned the string “hello world” to the variable myStr. We can also define an empty string that has 0 characters as shown below. myStr="" In python, every string starts with and ends with quotation marks i.e. single quotes ‘‘, double quotes ”” or triple quotes ...
There are a few different ways to define multiple lines of text as a single variable. The most common ways are:Use a newline character (\n). Use triple quotation marks (""").Newline characters separate the text into multiple lines when you print the output:Python Copy ...
Specifying the input values by dictionary mapping is especially useful if you want to define the data only once and you might switch the order of display in different outputs. Conclusion At this point, you’ve learned a lot about thestring modulo operator. It’s an older string formatting met...

Define the string that you want to insert into the original string. Index to Insert: index_to_insert=16 Determine the index at which you want to insert the new string. In this example, we chose the index 16. String Concatenation:
You can concatenate strings and integers using thestr()method. For example, first, define a string variablestring_valuewith the value"Welcome to SparkByExamples"and an integer variableinteger_valuewith the value2023. Thestr()method is then used to convert the integer value to a string, and th...
Extract a substringfrom a string. Use thestartandstopvalues to define the range. For example: quote = "There's no place like home." print(quote[3:10]) The code fetches a substring starting at index three up to index ten. Thestepvalue defaults to1when left out. ...

The example evaluates an object in the f-string. $ python main.py John Doe is a gardener The __format__ method The__format__method gives us more control over how an object is formatted within an f-string. It allows us to define custom formatting behavior based on the format specifier ...
